Review Summary
The SW115A 15" Active Subwoofer from Proel is a high-quality active subwoofer that provides exceptional bass response, ideal for use alongside full-range loudspeakers. The sub's 15mm beech plywood cabinet has a vented BPS (series-loaded band pass) configuration, which provides high efficiency and fast dynamic response. The internal Class-H amplifier delivers 350W of continuous power for a strong performance with low distortion.
The rear panel has stereo Neutrik XLR/TRS combo inputs, as well as XLR and 1/4" outputs for compatibility with a wide variety of speakers and sound systems. There is a selectable stereo crossover so you can match the sub to your speakers. There are also volume, phase and filter controls for further fine-tuning. A ground-lift switch eliminates hum caused by ground loops.
The SW115A is designed for terrific portability, offering a pair of integrated handles, plus a set of 4 wheels on the rear. There is also a 35mm pole socket, allowing you to mount a speaker on top of the subwoofer.
